round_durations represents the duration of rounds in seconds

create ~first_round_duration ~delay_increment_per_round creates a valid duration value

• parameter first_round_duration

  duration of round 0

• parameter delay_increment_per_round

  amount of time added in from one round duration to the duration of its next round

• raises Invalid_argument

  if

  • first_round_duration <= 1; or
  • delay_increment_per_round is <= 0

create_opt ~first_round_duration ~delay_increment_per_round returns a valid duration value Some d when create ~first_round_duration ~delay_increment_per_round does not fail. It returns None otherwise.

Warning May trigger an exception when the expected invariant does not hold.

round_duration round_durations ~round returns the duration of round ~round. This duration follows the arithmetic progression

duration(round_n) = first_round_duration + round_n * delay_increment_per_round
